Deployment use cases
Network Automation can be deployed on a small, medium, or large scale.
Small-scale deployment
A small-scale deployment comprises of one Network Automation application server with an embedded PostgreSQL database. The deployment involves running the Network Automation installer on the computer that will host the Network Automation application server and the Network Automation local device agent. The device agent and embedded database are installed as a part of the installer.
Highlights of a small-scale deployment:
- Requires a single host computer
- Includes database; no dependency on customer-provided Database Management System (DBMS)
- Devices are accessible to the application server
- Supports up to 25,000 network devices

Medium-scale deployment
A medium-scale deployment comprises of one Network Automation application server, a remote database, and multiple Network Automation remote device agents.
Highlights of a medium-scale deployment:
- Host computers required for the application server and each remote device agent
- Uses customer provided third-party DBMS
- Can support devices with overlapping IP addresses and devices in secure zones not accessible directly from the application server
- Supports up to 25,000 network devices

Large-scale deployment
A large-scale deployment comprises of multiple Network Automation application servers, remote databases, and multiple Network Automation remote device agents.
Highlights of a large-scale deployment:
- Host computers required for each application server and each remote device agent
- Uses customer provided third-party DBMS
- Can support devices with overlapping IP addresses and devices in secure zones not accessible directly from the application server
- Each application server supports up to 25,000 network devices
(Optional) TrueSight Network Automation – Multi-Server Administration, a console for the administrators who have multiple application servers (also called sites) in their environments. Using this console, administrators can perform the following tasks:
- Push content – Push various types of content such as combo groups and dynamic fields from one application server to multiple application servers.
- Search for devices – Search for devices across multiple application servers.
One Multi-Server Administration server can support upto 10 sites.
